2 Claims.

This application is a division of my prior application Serial No. 104,678, filed by me October 8, 1936 on a Reel and relates to subject matter originally presented therein.

This invention relates to reels of the dresser type on which yarn is wound preparatory -to warping, and relates more particularly to the Winding drum or cylinder used in such a reel. In the operation of the dresser type of reel, threads or yarns are brought to the reel from spools mounted in an adjacent creel and are secured to a section of the winding drum, which is then rotated to wind the threads or yarns on the drum. As the winding proceeds, the drum is fedslowly axially relative to the threads or yarns, so that the latter form a yarn section on the reel.

It is desired that this yarn section be diamondshape in cross section, and in order to attain this result, it has been customary to provide a Winding member of slatted construction, having a plurality of spaced bars at one end of said member which could be adjusted at Various angles to support the yarns and thus produce the desired diamond-shape section. Such constructions are shown for instance in the prior patent to Thiel No. 934,580, and in the prior patent to Mallison No. 513,431.

It is the object of my present invention to provide in a reel a Winding drum of improved construction, which preferably comprises a sheet metal drum having an enlarged truncated conical portion at one end thereof and which is permanently assembled therewith. A further object `of my invention is to provide improved means for securing the yarn ends to the drum.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form `of the invention is shown in the drawings, in which Fig. 1 is a sectional side elevation of a reel embodying my invention; and

Fig. 2 is an end View, looking in the direction of the arrow 2 in Fig. 1.l

Referring to the drawings, I have shown my improved winding drum mounted in a reel comprising a frame having end members l and Il, connected by a plurality of upper and lower cross beams I2 and I3. The frame is mounted on rolls l5 having V-shaped grooves and supported on rails I6 and l1. Suitable provision is made for advancing the reel along the rails to provide transverse feed during the winding operation.

My improved winding drum comprises a cylindrical shell 22, preferably of sheet steel, mounted on anged discs or supporting members 23 having hubs 24 secured to a main .drive shaft 25. The

shaft 25 is mounted in bearings 26 and 21 on brackets 28 and 29 secured respectively to the end Y members I0 and Il.

A gear 30 is mounted on the drive shaft 25 and secured to one of the flanged members 23, and is rotated by a pinion 3| which is mounted on a countershaft 32 and continuously rotated from any suitable source o-f power. The supporting members or discs 23 are provided with annular brake flanges 35, positioned for engagement by brake shoes 36 pivotally connected at 31 (Fig. 2) and forced outward against the brake flanges 35 by any suitable expanding means not shown her-ein.

The drum 22 is provided at one end with an annular conical portion 40 in the form of a hollow truncated sheet metal cone which is welded or otherwise permanently secured at its smaller end to the outer surface of the drum 22. as indicated at lll in Fig. 1, and which has its larger end portion secured in concentric relation to the drum 22 by a spacing ring 44. The ring 44 is mounted at the end of thecylinder or drum 22 and is preferably welded or otherwise permanently secured to the outer surface of the drum 22 and to the inner surface of the conical member 40.

I thus provide a drum having a continuous cylindrical winding surface and having a permanently assembled conical end portion which is ac1 curately concentric with the drum and which supports the yarn ends in such manner that successive sections A, B, C, D and E (Fig. 1) may be wound thereon, each having the desired diamondshape cross section.

In order that the yarn ends may be conveniently secured to the surface of the cylindrical drum, I provide the drum with a series of circular openings 50 (Fig. l) each having circumferential extensions or recesses 5I. Theyarn ends to be attached to a particular portion of the drum are assembled in groups and tied in knots which are then passed through selected openings 50 but which are too large to be drawn through either recess 5I. As the winding commences, the knots will be drawn into one or the other of the recesses 5| and will be firmly retained. By providing oppositely disposed recesses 5I, the yarn is firmly held, whether the drum is rotated clockwise or anti-clockwise.

The cylindrical sheet metal construction of my improved reel is a marked improvement over the Slat construction previously common and shown in said prior patents to Thiel and Mallison. The

supporting members 23, being spaced well inward from the ends of the drum, not only satisfactorily support the drum but also permit par-ts of the op erating mechanism to be mounted within the ends of the drum and to be effectively protected thereby. 'Ihe permanently secured and rigid construction of the corneal end portion 4D of the drum is also a substantial improvement over the loosely connected and widely spaced adjustable bars previously in use.

Having thus described. my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In a warping reel in which multi-thread sections of yarn are wound preparatory to warping, a yarn-receiving drum comprising a sheet metal cylinder and an enlarged truncated conical por- 20 tion mounted on said cylinder adjacent one end thereof, said conical portion being permanently secured to the outside of said cylinder at a point spaced from one end of said cylinder, said cylinder being provided with openings therethrough to receive the knotted ends of groups of warp yarns.

2. In a warping reel in which multi-thread sections of yarn are wound preparatory to Warping, a yarn-receiving drum comprising a sheet metal cylinder, an enlarged truncated conical FULTON RINDGE.
